Can you add a photo looking straight down and including the link piece and the cylinder? Jonathan

Don't think I've ever seen a value in a Guide or in the archives. I'd do it up gentle forearm tight, and check after a few days of use. Jonathan PS: There are generic tables of recommended values for bolt sizes and types.

From what you describe the fault is in the speedometer unit. There are two recommended repairers. Jonathan

Where are you? Jonathan (ex St Helens)

... the steering wheel gets turned 90 degrees to the left when going forwards just a few yards and about the same to the right when going backwards. ...alignment all checked, nothing wrong. Swapped driver's side wheels front-to-back... CURED! What did you conclude was the cause? Jonathan

Don't know, and it's not in the bolt list. Just been out to measure my nut: 23.9mm across faces. So probably 5/8". Jonathan

We had a horsey place in the next village... Stud farm? :-) Jonathan

Very neat. ... Mass of factory part (each): 270g. Mass of these (each): 50g. Moolah : mass = £27.50/(2*(270-50g)) = £62.50/kg. Jonathan

I'll have a look for low-pitched solid state noisemakers. For conventional designs I found these from e-Tech on Amazon UK: £19 with a mass of 2 x 195g. (Anyone ever weighed a factory horn?) Jonathan

Did you find DVA's advice? That's what I'd follow. Jonathan

Performance sounds great. Moolah : mass = £79/(3.9 - 2.9kg)= £79/kg. Jonathan

Previous discussion, including link to DVA's advice. Jonathan

Hadn't noticed the Soft Bits for Sevens tool bag before: http://www.softbitsshop.co.uk/ekmps/shops/juddltd/images/tool-bag-1033-p%5Bekm%5D300x168%5Bekm%5D.jpg Anyone got one? Jonathan

Anyone asked the factory yet? Jonathan

I wouldn't expect much degassing over the pressure excursions in a 7's braking system. But if compressibility is affected it might explain the reported effect. (My money's still against it.) Jonathan

If I were doing mine again I'd take advantage of the hard-won experience of BlatChat and use very strong Velcro-type stuff. Jonathan

If I read the thread correctly we're still not sure what the original bolts were. Do you have any of them removed and undamaged to help resolve that? Jonathan

Motte de loi :-), and you avoided the gazon trap. Loi de l'Emmerdement Maximum Jonathan

The only thing that failed in a 1600 mile trip was the indicator flasher unit, and I did not have one of those! What's the French for Sod's Law? Jonathan

Not convinced by the smaller bubbles but the solubility argument is interesting. What's the relationship between dissolved gas content and compressibility? I was wondering why professionals use negative pressure, and we use positive pressure. But that could be a different trade-off between capital cost and labour time rather than improved outcome. (Crossed with Oliver's costing.) Jonathan PS: I'm cautious about attributing superior performance to the last used method. See also finding keys in the last place you look. PPS: I worked with bubbles in two very different ways in my career. Bubble management was the technological breakthrough that led to the Technicon AutoAnalyzer. And that's what allowed cheap, widespread multichannel clinical chemistry analyses that most of you will have used as patients. It was eventually beaten by pre-existing conventional liquid-only systems that replicate manual techniques using pipettes and cuvetttes.

I haven't placed the latest order as I'm trying to get (much) lower shipping costs. Please add your request to that thread and they'll be included. Jonathan

It's rumoured that the Haynes manual for the MG ZR covers the VVC engine. Would that be appropriate for the VVC used in 7s? I have the non-VVC Haynes manual and the official Rover 'K' Series engine overhaul manual (RCL 0057ENG), which does include VVCs. Jonathan

Everything I see says there should be 3 holes on the adjustment, but I can only see 2 and its at the furthest. Haven't heard of that. Could you add a photo? Jonathan

I couldn't find a link to the sound of those CBS horns. There's a great site somewhere with hundreds of horns with linked sounds. But how can we add lightness? What's the equivalent of lithium batteries or LEDs? How about those alarms used in domestic smoke detectors? They're loud, attention-catching and very light. (I have a friend with residual tinnitus from getting close enough to switch one off!) Jonathan
